Question

A 0.5-kg ball accelerated at 50 m/s2. What force was applied?

Answer 1

Given,

The mass of the ball, m=0.5 kg

The acceleration of the ball, a=50 m/s²

From Newton's second law, the force acting on a body is equal to the product of the mass body and the acceleration produced due to the applied force.

Thus, the applied force is,

`F=ma`

On substituting the known values,

`\begin{gathered} F=0.5*50 \\ =25\text{ N} \end{gathered}`

Thus the applied force is 25 N
